These models are equipped with distributorless ignition systems. The spark plug wires are connected directly to the ignition coils. Additionally, Quad-4 engines don't have spark plug wires-the coils attach directly to the spark plugs. The spark plug wires should be checked at the recommended intervals and whenever new spark plugs are installed in the engine. The wires should be inspected one at a time to prevent mixing up the order, which is essential for proper engine operation. Disconnect the plug wire from the spark plug. To do this, grab the rubber boot, twist slightly and pull the wire off. Do not pull on the wire itself, only on the rubber boot. Check inside the boot for corrosion, which will look like a white crusty powder. Push the wire and boot back onto the end of the spark plug. It should be a tight fit on the plug. If it isn't, remove the wire and use pliers to carefully crimp the metal connector Inside the boot until it fits securely on the end of the spark plug. Using a clean rag, wipe the entire length of the wire to remove any built-up dirt and grease. Once the wire is clean, check for burns, cracks and other damage. Do not bend the wire excessively or pull the wire lengthwise-the conductor inside might break. Disconnect the wire from the coll. Again, pull only on the rubber boot. Check for corrosion and a tight fit In the same manner as the spark plug end. Replace the wire at the coll. Check the remaining spark plug wires one at a time, making sure they are securely fastened at the ignition coll and the spark plug when the check is complete. If new spark plug wires are required, purchase a set for your specific engine model. Wire sets are available pre-cut, with the rubber boots already installed. Remove and replace the wires one at a time to avoid mix-ups In the firing order.

Inside the boot of a spark plug wire, you should check for corrosion, which can appear as a white crusty powder. Ensure the boot fits securely onto the spark plug.

Push the wire and boot back onto the spark plug, ensuring a tight fit. If necessary, use pliers to crimp the metal connector inside the boot.

While cleaning spark plug wires, use a clean rag to wipe the entire length of the wire, removing any dirt and grease. Check for burns, cracks, and other damage during the cleaning process. Be careful not to excessively bend or pull the wire lengthwise to prevent conductor breakage.
